How to prolong the life of the volute screw press sludge dewatering machine

1. The equipment lacks regular maintenance
According to statistics, more than 80% of the failures of the screw-type sludge dewatering machine are caused by the lack of regular maintenance or improper maintenance of the dehydration main body. It can be seen from this that the establishment of a regular maintenance system for the dehydration body plays a decisive role in prolonging the service life of the screw stacking sludge dewatering machine and improving work efficiency.

2. The volume of mud feed is too high and the operation is overloaded
The amount of mud entering exceeds the normal processing capacity of the equipment, the internal pressure load of the dehydration body is too large, the friction between the movable ring and the screw shaft increases, and the movable ring and the screw shaft wear. Therefore, the reasonable amount of slurry must be adjusted according to the processing capacity of the whole machine to avoid overloading the operation.

3. The equipment has not been maintained before it has been shut down for a long time
If not cleaned when the device is shut down, sludge will remain between the movable and fixed rings. After a long shutdown, the residual sludge dries up and jams or jams the moving ring. Therefore, when the equipment is closed, especially for a long time, in order to avoid drying of the residual sludge between the movable ring and the fixed ring, the main body of the stacked screw sludge dewatering machine should continue to run for half an hour in strict accordance with the requirements of the operating procedures Above, if necessary, adjust the clearance of the backup platen to facilitate the discharge of sludge. After the sludge is completely emptied, the cleaning equipment can be shut down.

4. Wooden blocks, metal blocks or large slag blocks enter the dehydration body
Avoid hard objects such as large slag blocks, wooden blocks, and metal blocks entering the main body of the equipment. If necessary, add a filter device at the water inlet, otherwise it will cause the movable ring to freeze, and further cause the movable ring and the screw shaft to wear.

Therefore, in order to make the screw stacking sludge dewatering machine run continuously at high speed, high quality and low cost, the relevant personnel must do a good job in daily inspection, maintenance and maintenance of the screw stacking sludge dewatering machine to extend the main body and supporting facilities. service life.
